Can't contact LDAP server/connect error

Hi,

 

No changes on Firewall or LDAP server side. All of a sudden noticed for some virtual systems, LDAP server connection failed.

The LDAP is configured correctly and we have the read permissions for everything in AD user. 
Errors in usridd.log:

Any idea what is it indicating?

Hello,

 

Issue is resolved by unchecking the SSL box, committing, then checking the SSL box and committing again.

 

Thanks

have you tried disabling SSL on the ldap profile ?

 

try increasing the debug level:

> debug user-id on debug
> debug user-id set ldap all

this may provide you with more details

 

 

don't forget to unset debugging after you're done:

> debug user-id unset all
> debug user-id on info

i have the same messages:

2016-09-27 11:02:39.609 +0200 ldap cfg Pan_Grp connected to XXXXXX.domain.com:636(index 0)

 

looks like, it tries to connect with normal LDAP:636 and then successfully with LDAPS:636.  LDAP:636 will not work...

Checkbox "SSL required" is checked and it still tries LDAP:636 first...

Hi Hithead,

 

We opened a support case for this and now it is escalated to their engineering team. PAN support has suggested to upgrade to 7.0.10 and see if it addresses the issue.
